Yep, nothing I can do about their insidious ad square. Sometimes if I get lucky, my Google bar will trash it with the anti-popup feature and leave the screen clear.
Eventually I will get a domain instead, but keeping my personal details hidden from Whois is critical, and I haven't found a way to do that yet. And please, don't go saying "GoDaddy offers anonymous registrations" or whatever, as such a domain would, as ever, need to be 100% British owned and served without yankee interference.
